Problems solved by technology

[0009] However, in the method of Patent Document 1, once the ferrite is fixed by the holding member to the shape when it is attached to the protective frame, the position and shape of the ferrite cannot be freely changed.
Therefore, it is not possible to cope with the situation where, for example, it is necessary to attach the ferrite to other products with diffe

no. 1 Embodiment approach ）

[0051] use figure 1 , The structure of the rice cooker which concerns on 1st Embodiment of this invention is demonstrated. figure 1It is a side view which showed the rice cooker which concerns on 1st Embodiment of this invention in partial cross section. The rice cooker of the first embodiment performs rice cooking by electromagnetic induction heating.

[0052] Such as figure 1 As shown, the rice cooker of the first embodiment has a pot 2 and a substantially cylindrical rice cooker body 1 with a bottom, wherein the pot 2 is accommodated inside the rice cooker body 1 and accommodates cooked materials such as rice and water. On the upper part of the rice cooker main body 1, the lid main body 1a which can open and close the upper part opening part of the rice cooker main body 1 and the pot 2 is attached.

[0053] A protective frame 3 is provided inside the rice cooker main body 1 , and the protective frame 3 forms a storage portion for the pot 2 . The protective frame 3 is fo...

[0076] Image 6 It is the perspective view which has the ferrite unit of the rice cooker which concerns on 2nd Embodiment of this invention. Figure 7 It is a partial sectional view of the rice cooker of 2nd Embodiment of this invention. In addition, since the basic structure of the rice cooker of this 2nd Embodiment is the same as that of the said 1st Embodiment, description of the same part is abbreviate|omitted, and it demonstrates centering on a different point. In addition, the same code|symbol is attached|subjected to the same component as the rice cooker of said 1st Embodiment, and the description is abbreviate|omitted.

[0077] Such as Image 6 As shown, the holding member 8 of the ferrite unit 9 is made of an elastic material (for example, silicone rubber), and is insert-molded so as to cover the first ferrite 6 and the second ferrite 7 . Between the first ferrite body 6 having the chamfered portion 6 a and the second ferrite body 7 , a constricted portion (thin po...

Abstract

The present invention provides a rice cooker capable of improving the universality of the ferrite. The rice cooker of the present invention comprises a rice cooker main body (1), a pan (2)for containing the cooked materials, a protection frame (3) arranged inside the rice cooker main body (1) and used for accepting the pan (2), a heating coil (5) arranged at the external bottom of the protection frame (3) and used for sensing and heating the pan (2), a ferrite unit (9) which is arranged along the external bottom of the protection frame (3) and of which at least a part faces the heating coil. The ferrite unit (9) possesses a rod-like first ferrite (6), a second ferrite (7) and a keeping part (8), the keeping part (8) is connected with one end part of the first ferrite (6) and one end part of the second ferrite, and a part of the keeping part (8) between the first ferrite (6) and the second ferrite (7) is equipped with a hinging part (8c).

Description

technical field [0001] The present invention relates to a rice cooker provided with ferrite. Background technique [0002] In conventional rice cookers of this type, a high-frequency current is passed through a heating coil to generate a high-frequency magnetic field. The high-frequency magnetic field generates eddy currents on the surface of the pot, and Joule heat of the eddy currents is used to heat the pot. In a conventional rice cooker, ferrite (magnetic body) is usually attached from the outer peripheral side surface of the protective frame of a storage pot to the bottom surface. Thereby, among the lines of magnetic force generated when a high-frequency current is passed through the heating coil, the lines of magnetic force generated outside the pan are guided into the interior of the ferrite, thereby preventing leakage of the lines of magnetic force and improving inductive coupling with the pan. [0003] On the other hand, in order to appropriately heat the pan by in...
